.Net interview can surprise you with many diverse questions. However, with some preparation you can impress even the most demanding recruiters. See the popular .NET questions with answers to prepare for all the challenges that you may encounter on the road to a new, better job in IT.

.NET interview. Definitions you have to know

Interview for .NET developers requires a knowledge of several basic definitions that are especially useful for junior programmers. Senior developers should also keep them in mind during the meeting. Stressful situations can turn those simple .Net recruitment questions into an obstacle difficult to overcome. Recruiters usually tend to ask potential candidates about the definition of:

  • Repository – a central location in which data is stored and managed; it allows developers to implement improvements quickly and effectively.
  • Boxing – process of converting a value type to the type object or to any interface type implemented by this value type.
  • Unboxing – an explicit conversion from the type object to a value type or from an interface type to a value type that implements the interface.
  • Attributes – markers providing a way of associating information with code in a declarative way
  • TDD – software development approach in which a test is written before writing the code.
  • Garbage Collector – a component used for effective memory management.
  • Reflection – process allowing the program to be modified while running in a way depending on its own code.

Which .NET recruitment questions are the most popular?

Common .NET interview questions include identification of the differences between two things having a similar, but not the same meaning or use. That type of question is fairly popular. It helps the recruiter assess candidate’s knowledge of the given technology based on the practical experience. Usually that question involves the differences between the following concepts:

  • Var and dynamic
  • Value Type and Reference Type
  • Virtual and abstract
  • Lazy loading and eager loading
  • Ref and out
  • Interface and abstract class
  • FileStream and MemoryStream

Sometimes a candidate may have to answer a .NET interview question on a practical use of some technologies and tools usually combined with .NET in everyday work. Usually that type of question involves types of loops or tests. In some cases, prospective employees are also required to give a solution to a typical problem. That task may include listing the methods of improving website’s performance or risk prevention practices.

.Net recuitment tasks and questions: problems you may have to solve during the interview

The goal of .NET recruitment tasks is to practically test the knowledge that was already partially verified during the interview with the candidate. Usually those tasks include some of customer’s requirements that we need to fulfill in our code in order to succeed. That type of exercise is usually related to the project a candidate wants to join. Thus, it is easy to conclude that one should gather some information about the project before the .NET interview to prepare for the upcoming challenges.

There are also some other types of recruitment tasks that are overwhelmingly popular among .Net developers. Those tasks usually include spotting the mistakes in a code made by someone else or suggesting the improvements for a given program. Creating a code implementing a feature of recruiter’s choice is also a popular test for prospective programmers. That type of .NET recruitment tasks will be especially useful for Junior Developers – they are usually asked to create a code capable of displaying a string of numbers or removing the repeatitive words from a passage of text.

.NET interview: additional advantages

The sole knowledge of .Net is not enough to successfully complete a recruitment process.  Usually C# is required to successfully compete for the job in the field. However, there are a few additional advantages that could be beneficial for any .Net developer. Those include experience with HTML5, CSS3, JavaScript and TypeScript. The knowledge of SQL, React.js, Golang, Rust, GIT czy SPA will also be beneficial for those wishing to find their place in the industry.

Prospective .Net programmers should also have a basic knowledge of English language that is generally used in many companies working in international environment. An experience with Agile methodology will also be an additional advantage during a .Net recruitment process.
